Similarly, the OpenSSH client under Windows Subsystem for Linux (thin linux VM on windows) can be configured to use Pageant.Ĭheck out the WSL SSH Pageant github repo. Windows OpenSSH can be configured to use Pageant, and thus your hardware key.

Windows OpenSSH implements the SSH client used by both Windows Terminal (new command prompt) and VS Code SSH Remote Development Extension. Overall, just make sure you have all the keys on your local computer, and enable forwarding. It’s complicated, but a simple option to enable in putty. This is in contrast to using a SSH key stored on remote host one to connect to the second remote host. Your Computer -> Remote Host One -> Remote Host TwoĪgent forwarding means that, when connecting to the second remote host, an authentication agent (i.e., Pageant) from your computer can be used. So, it’s common to connect to a second remote host from a first remote host. If you have your git repo URL as a SSH connection (doesn’t start with HTTPS), then push operations will be done as a seperate SSH session. Communicating with the git server (e.g., github) can be done with HTTPS or SSH. It’s common to edit git repos in SSH sessions. Use the CAC flavor of putty to SSH into hosts, and it will automatically use the hardware SSH key where appropriate. This is what you need for github or the authorized keys file. To get the base64 text of the public key, click “copy to keyboard”. For information about using SSH private keys on Linux and OS X® operating systems, see Log in with an SSH Private Key on Linux and Mac. Note: These instructions apply to using PuTTY on the Windows® operating system.

The public key associated with the smartcard is now loaded into the putty agent. PuTTYgen: A tool for managing and creating SSH key pairs To download both tools, see Download PuTTY: latest release. Launch Pageant, and choose “Add CAPI Cert”, select your certificate and enter the pin. CAC refers to the smart card standard used for authentication in the federal governmetn. Putty-CAC is designed to use the native windows APIs for interacting with (physical) smart cards. Now we have a key pair on the virtual smart card. Microsoft Docs on New-SelfSignedCertificate Putty-CAC New-SelfSignedCertificate -Subject "CN=Gilroy Atkins" -KeyAlgorithm RSA -KeyLength 4096 -Provider "Microsoft Smart Card Key Storage Provider" Make sure to customize the name in the command below. However, we’re fine with a “self-signed” certificate. Normally, windows requires a whole mess of active directory servers, configured certificate self enrollment policies, certificate requests. Now we have a virtual smart card, but it’s blank. Microsoft Docs on tpmvscmgr.exe Self Signed Certificate tpmvscmgr.exe create /name VirtualSmartCard /pin PROMPT /adminkey random /generate /attestation AIK_AND_CERT Shockingly, it’s one command to create a virtual smart card reader and the associated card. The pin entry interface is provided by windows, and is (hopefully) secure. The virtual smart card lives within the secure element, and only encrypts/signs data in response to a pin. Most computers do have a TPM (trusted platform module), which can be used to implement a virtual smart card. However, few laptops have smart card readers. Smart cards are commonly used to store secret keys in hardware, where they can’t be exported. Microsoft makes it suprisingly easy to create and use a hardware SSH key (i.e., RSA key).
